Melted down my roommates small Honda radiator.
My roommate replaced his Honda radiator the other day and gave me his old one. There wasn't much on it besides some plastic and a single small brass pipe. So i decided to cut it up and melt it down using my small foundry i made awhile back. Started out a bit over 3lbs 12 ounces and ended up with a bit over 3lbs 1 ounce of pure aluminum ingots. There was about 4 ounces of dross left over and i guess the rest of the missing weight was just from grime and some flashing of the aluminum.
Edit: Unfortunately this forum won't let me upload pictures from links yet and the "manage attachments" option only allows 200 bytes max to be uploaded which is extremely small. Otherwise i would put up some pictures of the radiator and ingots.
